How you arrive at the ratings of your cc is not clear... kindly recap!!!!
Energy is neither created or destroyed, it just changes form.


120w of power can be 12v @ 10A or 24v @ 5A ( power = voltage x Amps, note layman assumption)

For efficiency in terms of cost you are better off with lower current (A) - This means smaller cable diameter, lower breaker amperageo

Hence for higher voltage and lower amps connect your pannels in series (the voltages add up, but current stays the same). So assuming youre connecting 3 units 120watts (17v, 7.05A) in series you will have 17+17+17Volts , 7.05A

At the charge controller these are the ratings you need to match

- the max PVoc your controller can handle - this gives you an indication of how many panels you can link up in series
- Your battery bank terminal voltage - your cc needs to match this

what your cc will be doing if its an mppt is convert the difference in volt from your string of PV (e.g 140v) and your battery bank terminal voltage(24v) to useful current for charging rather than dumping it as waste if it was a pwm


hope that helps

back to sleuth mode cool

Saipro:
I'll break my silence awhile. It's agonising to keep quiet at times in a random house.



If what you're after is an MPPT charge controller, I think most of the conventional ones handle about 150VDC VoC by default. Do the math from there.



I can testify it certainly works. I can as well assure you it's not for all scenarios or even most scenarios. Batteries damaged from abuse derive the least benefits while those which have either suffered neglect (sat a long time without charge) or had a few undercharge cycles seem to be its forte.



Desulphation is actually a plate thing while the charging current handles the mixing of the fluid. Many desulphators could be considered to be like modified PWM chargers (they need a charging source - whether coupled or inbuilt).

In the case of AGM batteries (in my personal experience), desulphation is not a straightforward thing and requires a lot of patience. I have used as many as 14 cycles of charging-desulphation-charging to get some back to nearly full capacity. About 25% of those sitting around for long have gained nearly full capacity. About 60 - 70% (depending on capacity and brand) have attained between 60 - 80% restoration. The remaining 5 - 15% were either unresponsive after numerous cycles or retained too little capacity to be of much use.

Specifically for the mythical AGM batteries (not sealed lead acid), I noticed :
1. Totally "dead" batteries often require a slightly higher than typical voltage and low current to "kickstart" the process.
2. Batteries of 55Ah and lower aren't good candidates. These respond more to controlled overcharging. Desulphators should be installed right from the onset else you'll have little or insignificant benefit.
3. Batteries 250Ah and above require industrial grade desulphators or those specifically labelled for such capacities. The regular desulphator would try your patience to the limit before getting the results you desire (works on the long run).
4. Open the cell caps (many AGM batteries are almost impossible to open without sawing off the top). If the cells are dried out, you're wasting time and other resources. I wouldn't recommend it but while experimenting, adding a sufficient amount of distilled water till the tops are no longer powdery (but not soaked) and leaving for a day or two (while connected to the desulphator but not charging) seems to give remarkably good results. Resume charging after 24 hours of "settling".
5. AGM batteries are tough to desulphate. Try at least 5 days of charging with desulphating-desulphating alone-charging with desulphating before you check for results (assuming your batteries are between 100Ah and 250Ah). Be mindful of the voltage rating and other manufacturer recommendations for your desulphator.
6. I've seen people trying to desulphate the small UPS batteries. I think it's a sheer waste of time (I've tried it too, just to be sure).

Feel free to add more to the list, based on your experience. That's the purpose of the forum.
And as Chris rightly noted, it is indeed like snake oil. For some, it works like magic; for others, baby oil would have been preferable to the nonsense called snake oil.
I was not referring to Voc but battery voltage @ 96v thank you

GTB charged me 253 to dollar yesterday huh huh
You folks just saved me N26,500! grin

Normally transact using GTB card though i have a stanbic linked to another paypal acct. Had to make a payment of $500 since friday, transfer from gtb to stanbic did not go through till this morning (guess stanbic was having issues with there online platform). Just had a feeling GTB was going to go ballistic so i just waited till i could transfer the funds. Just made the payment via stanbic...........(muttering to himself......choi N26,500! shocked )

What is the condition of the laptop?
The battery life, the screen, is the charger working?
Are all the hardwares and softwares in perfect condition?
condition is 9/10

hp battery check software reports the battery at 97% capacity indicating just a 3% wear! That is excellent in my opinion for a used laptop
